The principal object of my invention-is to provide a tie 'for metal straps in which metal straps of flat and substantially wide cross section after having been drawn tightly around a box may be attached together at their ends in such a manner that a strong joint or tie is provided which will not ordinarily pull apart under conditions of use.

A more specific object of my invention is to if? provide a tie for metal straps in which the ends of the strap are substantially overlapped and the overlapping portions of the strap are rolled transversely into substantially round cross section and crimped transversely it of the roll. I prefer to crimp the roll of the two overlapping sections of strap in such a manner that alternating annular or semiannular ribs and grooves are formed transversely of the rolled strap portions, and particularly so that the cross section of the rolled strap portions will be compact and interlocked so as to prevent the severing of the joint or tie.

It is an object to provide a tie in which an- 25 nular or semi-annular ribs may be formed on the periphery of the rolled strap portions in inter-locking relationship such as by providing a series of ribs and grooves 011 one portion of the roll, and another series of ribs and grooves on another portion of the roll which inter-lock with and are staggered with respect to the rolls on the first mentioned portion.

Other objects will appear as the descrip- "3 tion progresses.

In the accompanying drawings I have shown a form of tie for metal straps embodying my invention in which Fig. 1 is a top plan view substantially en- J larged of a metal strap with the ends thereof tied together.

Fig. 2 is a side view of the tie shown in Fig. 1. Fig. 3 is a bottom View of the tie shown in Fig. 1.

Fig. 4 is a modified form of tie.

Fig. 5 is a transverse section of a tie as shown on line 55 of Fig. 1.

Fig. 6 is a view similar to Fig. 5 showing ne a modified form of roll.

My invention comprehends a tie such as is shown in Figs. 1 to 4 inclusive which is adapted to be formed on substantially flat metal-straps 1 intermediate the ends 2-and 3 of the strap after the strap has been ten- :55

sioned around a box,' crate, bale, or the like.

The tie 4 is formed intermediate the ends 2 andB and is substantially elongated but sufficiently inwardly of the ends 2 and 3 as to permit said ends, when the tie is completed 69 to rest fiatwise against the bodyof the band 1, as-shown for instance in Fig. 2. The tie 4 is formed by rolling the intermediate portions'of the overlappedends 2 and 3of the strap transversely, the two overlapping por- '05 tions of the straip'ibeing rolled about a common axis. In the formation'of the tie 4 the initial "operation would consist in rolling the overlapping portions ofnthe strap, andfinally the two rolls, whenwcompactly formed as 173 shownrin Fig. 51,, are crimpedtransversely of the :I'rolls so as :toanter-lock and retain'the rolled portions intheir tied positions.

.Asshown in Figs. 1, 2 and 3,.Imay by suitable means iform therolls 5 and -6 of 75 the tie 4 with v a: series of I alternating peripheral ribs :7, 7 etc.,' .and grooves-8, 8 etc., while on the oppositeside ofithe tie at I may provide :a series .of. similar peripheral ribs 9 andygrooves :10. Preferably the grooves .s' 8 and 10 are slightly :narrower thanitheribs Tend? so that as shown inrFig. 'l-the grooves :10, for instance," may extend for a1short distance into the adjacent ribs 7, thus providing portions 11, 11 etc; at the junctions 5-5 softhexrib'sr'and grooves whichserveto substantially reinforce the tie :and prevent the ends "of thel-strap frornbeing severed under strain.

In .theform of-tiedescribed-it willbenoted that-theribs and grooves on one-half ofthetie are staggered with respect to the ribs and grooves .on the other side ofthe tie.

- Intermediate. the extremities of .the tie 4 andt-he ends 2.and .3 of the strapl I pro- 'v-i'de sufiiciently lengthenedportions '12 and 13 which are flared-outwardly from the we tremities of the tie to the ends of the strap so that the portions 12 and 13 may be'jgradually shaped from the rounding "form of the rolls into the flat cross section of the strap, as shown in Figs. 2 and 3.

As shown in Figs. 5 and 6, the outer edges 14 and 15 of the rolled portions of the tie either substantially abut or overlap the opposite edges 16 and 17.

As a modified form of tie I may provide, as shown in Fig. i, a series of V-shaped or triangular ribs 18, 18 etc., and grooves 19, 19 etc., in which arrangement the grooves 19 will inter-lock with the ribs 18. In this form of tie the ribs 18 and grooves 19 may be continuous around the periphery of the tie 4, or there may be two series of such ribs and grooves to correspond to the transverse ribs and grooves of the form shown in Fig. 1.

I also conceive it possible to arrange the ribs and grooves in helical form around the ties 4:, or otherwise, without departing from the spirit of my invention, it being only necessary to reinforce; and inter-lock the rolled portions of the tie so that they will withstand the tension and strain of usage.

What I claim is:

1. A tie for connecting the overlapping ends of a metal strap comprising two rolls of metal formed on a common axis and extending longitudinally of the strap but intermediate the ends thereof, the end portions of the strap being flat and engaging the flat body of the strap, and the portions intermediate the ends of the strap and the extremities of the tie being gradually flared outwardly as described.

2. A tie for connecting the overlapping ends of a metal strap comprising two rolls of metal formed on a common axis and extending longitudinally of the strap but intermediate the ends thereof, the end portions of the strap being fiat and engaging the flat body of the strap, and the portions intermediate the ends of the strap and the extremities of the tie being gradually flared outwardly as described, the peripheries of said rolls being correspondingly crimped transversely of the rolls to provide interlocking peripheral portions so as to prevent longitudinal movement of one end of the strap with respect to the other.

3. A tie for connecting the overlapping ends of a metal strap comprising two rolls formed on a common axis and provided with transversely inter-locking crimps on the peripheries thereof for preventing the relative longitudinal movement of said rolls.

4. A tie for connecting the overlapping ends of a metal strap comprising two rolls substantially overlapped at their opposite edges of circular cross section and formed on a common axis, and a plurality of alternating ribs and grooves formed transversely on the peripheries of said :rolls, the ribs and grooves of one roll inter-locking with the ribs and grooves of the other roll for preventing the relative longitudinal movement of the roll.

5. A tie for connecting the overlapped ends of a metal strap consisting of two rolls formed on a common axis with the opposite edges substantially overlapped, opposite portions of the peripheries of said rolls being formed with alternate ribs and grooves transversely of the rolls, the ribs and grooves on one portion of the rolls being staggered with respect to the ribs and grooves on the other portion of the roll, the grooves of one of the series at the junction of the two series of the ribs and grooves projecting into the ribs of the adjacent series for reinforcing the tie.
